Hi All,In an effort to write reusable code, I wrote the function below that will query a feature layer (url paramater) by a polygon (poly parameter). This way I don't need to have a separate query and actionscript block for each feature layer that I'll query. The problem that will happen is that when the function is called multiple times in a row the second query will begin before the first one has completed because it's asynchronous. At that point I'm not sure how to know which result is which. I really want to avoid having to write a black of code for each specific query, but when I try to generalize it, like the example below, I'm running into the asynchonous issues. Does any body have any ideas to handle this or a code example of a better way? Is there a way I can understand which result is which?Thanks,Chuck
private function FilterAttributeTablesByPolygon(poly:Polygon, strURL:String):void
{
querytaskFeaturesByPolygon.url = strURL;
queryFeaturesByPolygon.geometry = poly;
querytaskFeaturesByPolygon.execute(queryFeaturesByPolygon);
}
protected function querytaskFeaturesByPolygon_executeCompleteHandler(event:QueryEvent):void
{
// highlight the selected features - NOT DONE
var fs:FeatureSet = event.featureSet;
var attributes:Array = fs.attributes;
var al:ArrayList = new ArrayList();
for each (var objRec in attributes)
{
al.addItem(objRec);
}
//code continues....
